SumizAI and AppFlowy side by side: price, licence, platforms and what each one actually does. ## What AppFlowy is AppFlowy is an open-source, openly declared alternative to Notion, built around giving users full control over their own data. The app combines documents, databases, kanban boards, calendars, and a wiki in one tool, running natively on macOS, Windows, Linux, iOS, and Android from a single shared codebase. Key features: The architecture relies on Flutter for a cross-platform, native interface and Rust for a fast, memory-safe backend handling application logic — that combination translates into a fast app start and near-instant page loading, even with large databases. Full offline mode lets you work without an internet connection and sync changes once it's back. AI integration with configurable language model providers adds writing assistance without sending data to one vendor-imposed cloud. Data ownership as a founding principle: Users have full (100%) control over their data — AppFlowy can be self-hosted on your own servers, setting it apart from Notion, where data always lands on the company's infrastructure. Open source code under the AGPL-3.0 licence also lets you modify the app itself to fit your own workflow. Who it's for: AppFlowy appeals to individuals and teams who value Notion's flexibility — documents, databases, kanban boards in one place — but don't want to hand their data to a third-party company or be dependent on its business decisions about pricing or service availability. Use cases: In practice, AppFlowy works well for building an internal team wiki on your own server, managing projects through kanban boards and relational databases, and migrating away from Notion for organizations with data-location compliance requirements. Pricing and business model: AppFlowy runs on freemium — the open-source, self-hosted version is entirely free, and the company also offers a paid cloud version for people who'd rather not manage their own server infrastructure. Limitations and what to watch for: Self-hosting means taking on responsibility for backups, updates, and server security yourself — for teams without a dedicated IT department, that can be a meaningful extra operational cost compared to a ready-made cloud service. AI plugins with a configurable provider: Rather than locking users into one built-in model, AppFlowy lets you configure your own language model provider for AI-assisted writing features — meaning data sent to the model goes exactly where the user decides, not to a default, vendor-imposed external service. Databases as the heart of the workspace: Beyond plain documents, AppFlowy offers relational databases with configurable fields, filters, and views — a feature especially valuable for teams managing structured data, like task lists with assigned people, deadlines, and priorities, rather than just loose text. A community of ready-to-use templates: AppFlowy users share ready-made workspace templates — from trip planning to project management — letting new users start right away with a sensible structure instead of building everything from scratch after the first login. AI notes in AppFlowy's database: AppFlowy has no built-in integration with chat models beyond its own writing assistant, but a fragment of a conversation with an external AI model can be pasted as a document or database entry and connected to other elements in the workspace — for anyone building an archive of ai notes in a Notion-like environment, that's a natural extension of the existing structure, though it requires a manual pasting step. Comparison with the original Notion: The main difference from Notion isn't in features — both apps offer a similar set of documents, databases, and views — but in who controls the infrastructure holding the data, which matters when assessing the business risk of depending on a single cloud vendor. What's worth checking before choosing: Before settling on AppFlowy, check whether you'd rather self-host with full control or pay for the company's cloud version, and test migrating your existing Notion base to gauge how much manual work the move requires. One codebase, many platforms: Thanks to Flutter, the same interface code ships to desktop, phone, and tablet with no separate versions maintained in parallel by the team — for users that means a consistent experience regardless of device, and for the developers, faster rollout of new features across every platform at once instead of one at a time. Community around the open code: AppFlowy is developed by an active community of contributors submitting fixes and new features directly to the GitHub repository — for an organization with its own technical team, that opens the door to shipping custom modifications without waiting for the official roadmap from the company behind the project. Migrating from Notion step by step: Moving an existing base from Notion to AppFlowy requires exporting the source data and importing it in the new format — the process tends to be smooth for simple documents, but more complex databases with elaborate relations and formulas may need manual cleanup after migration before everything works exactly as it did before. A trade-off between control and convenience: Choosing between self-hosting and AppFlowy's paid cloud is, in practice, a choice between maximum control (and responsibility) and the convenience of a ready-made service — there's no single right answer, only a trade-off that depends on a team's technical resources and how much weight it puts on independence from an outside vendor. Bottom line: AppFlowy is an open-source, self-hostable alternative to Notion with native performance thanks to Flutter and Rust. Anyone who wants ai notes from AI conversations to land automatically as plain files without having to build their own database structure should consider a tool built around that workflow. Comparison with SumizAI: AppFlowy and SumizAI differ in model and content source. AppFlowy is a flexible, self-hostable platform for hand-written documents and databases, with optional AI writing assistance. SumizAI generates ai notes automatically from a conversation with an AI model connected through your own API key to one of seven providers, saving them as Markdown files in a folder you own. Anyone who wants a full-featured workspace platform with databases and kanban boards will pick AppFlowy; anyone who wants ai notes to arise directly from an AI conversation without building the structure themselves will find SumizAI the better-fitting tool. **Key facts** - Price: Freemium - License: Open Source - Origin: Singapore - Category: Note-taking, Todo List Manager ## What SumizAI is A note-taking application built around a conversation with an AI model. You ask a question, the answer streams back, and the answers worth keeping become Markdown notes — filed into a vault that is a folder on your own disk. A vault is a directory holding `base.md`, a generated table of contents up to six levels deep, and a `notes/` folder with one `.md` file per note. Before a note is written it is checked against the ones already there, so the fourth note about the same idea gets merged instead of added. Links between notes are ordinary Markdown links to files that exist. The model is never ours: you bring your own API key to one of seven providers — Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server — and pay that provider directly. A question sends the table of contents plus at most five relevant notes within a 24,000-character budget, and the app shows you which five it used. ## Where they differ - AlternativeTo's description of AppFlowy does not mention an AI model. That is the whole starting point in SumizAI: you have a conversation with a model on your own API key, and the answers worth keeping become notes without you filing them. - AppFlowy is open source (AGPL-3.0), and SumizAI is not. If reading the source is what decides it for you, that is a real argument for AppFlowy. The guarantee SumizAI offers instead is structural rather than legal: the notes are Markdown files in a folder you chose, so they open in any editor whether or not the application is running. - AppFlowy is freemium: there is a free tier and a paid one, and the line between them is the thing to read before committing. SumizAI has one plan at a dollar a month, so there is no feature held back for a higher tier — and an unpaid account still opens and exports every vault it already has. - AlternativeTo's description of AppFlowy does not mention Markdown, so check what format your notes end up in before you fill it up. SumizAI writes standard `.md` files to a folder you picked, and an unpaid account can still export all of them. - AppFlowy is described as something more than one person uses at once. SumizAI is not: there are no shared vaults, no comments, no permissions and no sync between devices. If the work is a team's, that is a reason to pick AppFlowy over SumizAI. - AppFlowy can be self-hosted. SumizAI has nothing to host on the desktop — the vault is a folder on your machine — and if you want the model on your own hardware too, a local Ollama is one of the seven providers it speaks to. - AppFlowy is extensible through plugins. SumizAI is not, and that is a genuine trade: you cannot bend it into something else, but there is also no plugin to keep working after the next release. What it does instead is fixed and small — a chat, a filing rule and a folder of Markdown.
